END PLATE FOR CUT-OUT VALVES.

Application filed June 25, 1921.

To all whomy t may concern."

Be it known that I, ELMER RYDER, a citizen of the United States, residing at Argo, in the county of Cook and State oi Illinois, have invented new and useful Improvements in End Plates for Cut-Out Valves, of which the following is a specification.

This invention relates to improvements in cut-out valves for exhaust pipes of engines for automobiles and other motor vehicles.

In my copending application, Serial No. 424,068, filed November l5, 1920, I have shown and described a cut-out valve structure which may be applied to an exhaust pipe without cutting the same in two. Ex-

-haust pipes of cars of different makes do not have the same diameter, but vary from the smaller size as used on a Ford to the larger sizes as used on other makes of cars.

To enable said cut-out valve fitting to be applied to these exhaust pipes without making it necessary to make different sized fittings, is the object of my present invention, and in accomplishing such object I make the fitting of one standard size and use therewith sets of interchangeable end plates to fitagainst the pipes atthe ends of the fitting and make proper joints at such points. To dothis the end plates have their inner edges curved or concaved to conform to the transverse curvature of the various sized pipes, the curvature of said edges being made on radii of the different sized pipes, so that withr one set of plates the fitting may be'applied'V to an exhaust pipe of one diameter, and with another set of plates to an exhaust pipe of a different diameter, and so on, there being a set of end plates for each size of exhaust pipe.'

In the accompanying drawings- Fig. l shows said valve fitting applied to an exhaust pipe and equipped with end plates made yin accordance with my invention and having curved inner edges to conform to the transverse curvature of said pipe, the parts being shown in vertical longitudinal section;

Fig. 2 is a top plan view of the parts shown in Fig. l;

Fig. 3 is a vertical sectional view taken on line 3 3 of Fig. 1; and

Figs. 4 and 5 are side elevational views of two end plates having the same size lengthwise, but provided with inwardly curved edges on'different radii.

Serial No. 480,337.

In the drawings, l indicates an exhaust pipe, and 2 the casing of my said cut-out valve fitting. This casing is shaped somewhat like an elbow and has a single passage extending therethrough. Bef'ore the fitting is applied to the pipe l, a rectilinear opening 3 is cut in the same, and the fitting is applied to said pipe over said opening. The single passage in said casing opens at its inner end into said pipe l through said opening 3 and at its outer end through an integral extension 4 with which the casing is provided. To this may be connectedv a pipe 5, which pipe may lead to a heater in the floor of the car, when the exhaust gases are to be deflected to the heater for warming the interior of thecar in cold weather, or the pipe 5 may be open to the atmosphere, when the valve device is used purely for cut-out purposes.

The casing 2 has an integral lug 6 at its base. This lug projects inward and provides a bearing for a valve stem 7, which extends across the passage in the casing and into the exhaust pipe l through the opening 3. Secured to the stem 7 are two disk shaped valve members 8 and 9, one -in the casing 2 and the other in the exhaust pipe. The valve members 8 and 9 are arranged at right-angles to each other, so that when one is fully opened the other is fully closed. The stem 7 projects out through the casing 2 so that suitable operating mechanism may be connected with it for opening and closing the valves from. a point on the dash-board or near the drivers seat.

The base of the casing 2 has the saine shape as the opening 3, only larger,vand the side edges of the base engage against the pipe l along the side edges of said opening, there being a gasket l0 inserted between such parts to make a leak proof joint. The end flanges il, ll ofthe casing are over the end edges of the opening 3 and curved inward or concave on a radius equal to that of an exhaust pipe of the smallest diameter used on a car, so that when the casing is applied to such an exhaust pipe said edges of the end flanges 1l, 1l will fit against the exhaust pipe along the corresponding edges of the opening 3 and against the portion of a gasket, such as 10, interposed between such parts. The fitting is clamped to the exhaust pipe by a U-shaped clamp bolt l2 extending around and under the exhaust vpipes of different sizes.

pipe and having its ends inserted through ears 13, 13 on opposite sides of the casing, as shown in Figs. 2 and 3.

' Vhen applying the fitting to an exhaust pipe of a larger diameter than that just mentioned, the curvature otthe edges of' the end flanges 11, 11 would not conform to the curvature of such exhaust pipe, and to make a gas tight joint between said end flanges and an exhaust pipe of that diameter, I employ. asetiot' end plates 14,14. These are secured to the. end flanges `11, on the outside thereof, bygscrews 15, and have their inner edges curved or concave on a radius equal to that of the particular exhaust pipe with which they are used, so as to coliform to the outer curvature of the exhaust pipe offthat diameter and bearl against the` interposed portions of the gasket 10. When applying the fitting to an exhaust pipe having a larger orsmaller diameter than that mentioned, I secure to the end flanges 11 of the same fitting end. plates having their inner edges curved on radii corresponding to the diameters of the pipe with which they areused. For example, in` Eig. 4I have shown an end plate 16 having its inner edge curvedto conform to the curvature of. an exhaust pipe 17of` a diameter lless than that shown in Fig. 3, While in Fig. 5 I have shown an end plate 18` having its inner edge curved on a largerradius so as to conform to the curvatureof an exhaust pipe .19ct a-diamcter greater' than either of the ones shown lin the preceding figures.

The end plates are interchangeable with the fitting and thus permitthe latter to be made one size and usable with exhaust This adapts the fitting to all makes of oars and avoids the necessity and expense of making and handlingv as many sized lfittings as there are different sized exhaust pipes. The advantage of my construction will thus be manifest.

I claim my invention:

l. The Combination with an exhaust pipe having a rectilinear opening in its Wall, of a cut-out valve `fitting applied to said pipe at said opening, said fitting having an outer casing provided with substantially straight side edges to engage against said pipe along the side edges of said opening and with its ends at the end edges of said opening, the end edges of' the casing being curved inward on a radius less than that of said pipe, plates secured to the ends of said oasing and having their `inner edges curved inward on the same radius as said pipe to conform to the `transverse curvature of the pipe and fit against the same adjacent the end edges ot' said opening, and means for clamping said casing on said pipe.
